Overview
Gardermoen sentralrenseanlegg serves the Akershus region of Norway, treating wastewater for approximately 47,500 people. The plant operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Gardermoen sentralrenseanlegg is a wastewater treatment plant located in Ullensaker, Akershus, Norway, serving a population of around 47,500. Situated near Oslo Airport Gardermoen, the plant is a key part of the region's water infrastructure, handling municipal wastewater from the surrounding communities. As a Norwegian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which Norway implements through its national regulations. For agglomerations of this size (between 10,000 and 100,000 population equivalent), the directive requires secondary treatment as a minimum, with more advanced treatment needed if the receiving waters are sensitive to eutrophication. The treated effluent is discharged into local water bodies that eventually drain into the Oslofjord, a significant marine ecosystem. The Oslofjord supports diverse aquatic life and is an important recreational and ecological area. The plant's performance is critical for protecting water quality in this sensitive coastal environment.
Environmental context
The plant's treated wastewater flows into local streams and rivers that drain into the Oslofjord, a large fjord system connected to the Skagerrak and the North Sea. The Oslofjord is an ecologically sensitive area that supports diverse marine life, including fish populations and migratory birds. Nutrient loading from wastewater can contribute to eutrophication, making effective treatment essential for maintaining water quality and ecosystem health.
Frequently asked questions

The plant serves approximately 47,500 people in the Akershus region, including the municipality of Ullensaker and surrounding areas.
The treated wastewater is discharged into local water bodies that flow into the Oslofjord. The plant's discharge is regulated under Norwegian environmental law to protect the fjord's water quality.
As a Norwegian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), implemented through national regulations. For its population size, secondary treatment is required, with potential tertiary treatment if the Oslofjord is designated as a sensitive area.
Under the EU Urban Waste Water Treatment Directive, agglomerations of 10,000 to 100,000 population equivalent require at least secondary treatment. In Norway, many plants also incorporate nutrient removal to protect sensitive coastal waters like the Oslofjord.
